Be it known that I, Ilinnirunrv R; BAILEY, a citizen of the United States, residing at Clarinda, in the county of Page and State of Iowa, have invented cert-ain new and useful Improvements in Centrifugal Separators; and I do declare the following to'be a full, clear', and exact description of the invention, such as will enable othersv skilled in the art to which it appertainsto make and use the same.

This invention relates to improvements in centrifugal separators and particularly to centrifugal cream separators.

The invention consists in the construction and arrangement of parts as wilbe hereinafter described and particularly pointed out in the claim. 'y

In the accompanying drawings: Figure 1 is a vertical sectional view through a separator showing my improved separating disks arranged therein; Fig. 2 is a perspective view of one ofthe disks; Fig. 3 is a sectional view of the same; Fig. 4e is a perspective view of another form of the disk; Fig. 5 is a similar view of stillanother form of disk; Fig. 6 is a vertical sectional view of a modified form of separator wherein the separating devices are in the form of hinged blades or wings; Iig. 7 is a horizontal sectional View of the same with part of the wings orblades removed; Fig. 8 is a side view of one of the separating blades or wings; F ig. 9 is a similar view of another form of the blades.

Referring more particularly to the first five figures of the drawings, v1 denotes the separator bowl in which is arranged the usual liquid supplying tube 2. The tube 2 is open at its upper end to receive the liquid which is fed thereto from any suitable form of hopper. Ihe bottom 3 ofthe bowl 1 is of conical form and in the tube 2 adjacent to the central upper portion of the bottom is formed a liquid discharging passage 4 through which the liquid is discharged and falls onto the bottom 3 and is conducted' thereby to the lower Aportion of the sides of. the bowl 1, up which the liquid is caused to travel by the centrifugal force derived from the rapidly revolving bowl.

Arranged on the tube 2 within the bowl l are 'my improved liquid separating cone shaped disks 5 which are spacedapart and arranged one above the other as shown. disks -5 have formed in n;

notches 6 which are engaged with radial vertically disposed bars 7 arranged 'on the tube 2 whereby said disks are secured infproper relative posit-ion on thetube.- AIn the upper portie-1i of the bowl ,1 above theseries of separating disks is arranged a skimming cone 8 which may be of' the usual or-any suitable construction whereby the heavier@ parts of the liquid which are forced up the inne-r sides of the b owl by the centrifugal motion thereof are caught and directed to a suitable discharging passage 9 formed in one side of the upper portion or neck of the bowl as shown. The lighter parts of the liquid which are caught by the separating disks 5 are carried thereby against the centrifugal force of the machine to the upper inner ends ofthe disks and are forced upthe outer surface of the tube 2 into a discharge chamber `10 arranged over the upper end of the skimming cone 8 and from said chamber is discharged through a suitable passage 11 formed in one side, of the neck of the bowl as shown.

My improved separating disks as shown in the first five figures of the drawings are of frusto-conical shape and o n the sides of the same are arran ed liquid ldirecting ribs. These ribs may be fiirmed separate from the disks and l secured thereto in any suitable planner or as shown inthe drawings the ribs may be pressed or struck into the metal of the disk 6 forming corrugations. In' Figs. 2 and 3 of the drawings are shown straight diagonally arranged ribs 12 which are strucky or pressed into the metal from the outer side and are arranged in parallel relation around the disks.4 The ribs when thus formed project below the inner wall of the disks to a suilicient extent for spacing the disks apart the proper distance for forming liquid conducting passages between the disks. In Fig. 4f of the drawings are shown ribs 13 which are constructed in the same manner as the ribs 12 s hown in Figs. 2 and 3, said ribs 13, however, being formed in spiral curves around the disks as shown. In Fig. 5 of the drawings the disk is shown as being provided with ribs 14 formed in upper and lower rows, the ribs in said rows being arranged in staggered relation. The variously arranged ribs as above described are preferably tapered or diminish in width toward their upper ends as shown.. The ribs may be continued through the lower edges of the disks as shown in Figs. 2 and 3 or said ribs I In assembling the in the bowl ofthe separator they are so arranged that the corrugations or ribs of one disk will come be:

tween' the ribs of the next adjacent disk so y t tsaid ribs will not nest together, but will engage; the surface of the under disk between therib's, said ribs thus forming supports by y whichlthe disks are spaced the proper dis: -tance apart. In thus arranging the disks carried up` the and ribs the cream or lighter part of the liquid beingrse'parated will, when caught-by the disks be carried or directed upwardly and inwardly toward the center of the disk and against' the centrifugal force of the rapidly revolving bowl, said ribs thus greatly vfacilitating and expediting the separation of the lighter' parts of the liquid from the against the'- outer sides of the bowl and' are same inthe manner described. y In Figs. 7, 8 and 9of the drawings is shown a modified form of separator comprising\a bowl 15 having a conically shaped bottom 16 and acentrally disposed feed tube 17 similar to the bowl and tube shown in the iii'stfigure of the drawing. Secured to the feed tube 17 andspaced a suitable distance a art are upper and lower blade supporting rings 18 to which are pivotally connected the inner edges of a series of curved wings or yheavier parts which are thrown outwardly blades 19 of which there may be any desired number, said blades being arranged substantially as shown in `Fig. 'l' of the drawing. Iiieach of the blades 19 is formed a series of upv.I ,rdly and inwardly inclined ribs or corrugations which are preferably struck into the material forming the wings. In Fig'. 6 of the drawings the wings or blades are shown as being' provided with straight in# clined ribs 'or corrugations 20. whilein Fig. 8, the blade is shown as being provided with curved ribs 21. In Fig. 9 the wing is shown as being provided with long ribs 22 between which at the outer edges of' thewings is arranged the snort ,ibs 23. The long ribs 22 are preferably f o' ined on a curve as shown. The ribs or deflecting elements are formed by indenting .the separating device from the upper sidethereby facilitating cleaning, and as they taper toward their inner ends, the escape of the particles taken up thereby is hastened while the spaces between them are reduced at their outer ends where there is greatest need for a large number of elements to act on the liquid and separate the com ponent parts thereof. The construction employed furnishes a positive means for preventing the lagging of the liquid in the bowl without adding to the weight of the lining or increasing the number of the parts and also effectually separates the disks in their spaced relation.

I wish it to be understood that the wings shown in Figs. 6, 7, 8 and 9 are provided on their inner faces with perforated, bearings 25 and that rods 26, are inserted through the perforations of the rings and those of the bearings so as to pivot the wings in position on the tube.

Having thus describedmy invention, what I claim is:

A centrifugal separator comprising the bowl with a liquid supplying tube having perforated rings thereon, blades having ribs of different lengths struck outwardly therefrom, the shorter ribs being arranged between thelonger ones, said ribs being constructed tapering throughout their lengths, said wings having bearings on their upper and lower inner faces, and rods inserted- EDGERLY n.
